,To rALL WiroM IT MAY ooNcEnN: v y

Be it known` that I, HENRY W. BAILEY, of' Springfield, in the county of Hampden and State oi' Massachusetts; have made and invented certainA new und useful Improvements in the Formation and Construction of" Sockets; and Ido herebydeclare that the following is a full, clear, and exact description ofthe manner of forming and constructing the same, referenceheing'hudto the annexed drawings, making a part of thisspeci- Figure 1 is a. longitudinal section, result of one heat, and Figure 2 a perspective view, result of' two heats. Figure 3, a vertical section of the punch A and die B.

Figure 4, an end elevation of the die B.

Figure 5, a bottom view orplan of the punch; and

Figure 6 aplan'of the die B;

Figure 7, a lateral or cross-seetion o'fthe punch Aand die B.

My invention relates'to certain improvements in dies for the formation and construction of Sockets on hammers, hatchets, adzes, or any tool having an eye, and provided with a socket around the same for the insertion and support ofa handle. i' 'i As heretofore practised in the manufacture of such tools, a bar of iron or steel, of nearly the same width as the head and socket combined, is heated and punched to form the eye c, a small punch being first inserted,

and larger ones successively, till the eye is of proper dimensions.- As punches of five diierent sizes are usually employed, and heating is necessary at eacfh successive punching, the forming of the eye thus requires tive heats'. Thehead ais-then cut down at each end of the eye e, thus forming or leaving the socket b, which is'afterwards drawnout" a. `little on a niundrel` andinished with swages. These latter operations require from two to four heats, thus necessitating from seven to nine heats in forming the eye and socket.

The dies invented by me are designed to obviate the necessity of heating so many timesfand also of cutting away and fasting the stock Iin forming the socketl; vand in carrying out my invention, I provide asteel die,

having across itsface a. groove, slightly vider and somewhat deepcr than the respective width and depth-of the p bar of which the head a' is to be formed; and abontmidway oi' the groove, b'utdecper, and below the same, I

construct and provide the diewith a matrix of about the sume size andshape 'as the exterior of the socket to ho formed therein. ,I also provide a; punch, A, of the proper size and length to form the eye e, which punch I `place in a"drop, and soarrange the die B that when thedrep' descends the punch falls directly in the middle.

of thematrix, but is preventedfrom touching the bottom by theshoulder'ofthe punch A, Figure 7. I then heat a. bar of ironor steel to a properdegree, and place it in the 'channel across the face of' the die. I then raise the drop and let it fall, when the punch not only pierces the har composing head g, lthus forming the eye e, hut'at the'sa-me time drives a part of the stock or har throughinto'the matrix or die, and forms the socket b, as far asy seen4 in iig. ,1, whichisa'sectional view of the Ahead, eye, and `socket, resulting from one heat or operation.

Reheating the head a, `insert a cold-chisel in the hole formed by the punch, and at a. blow I open the eye on the outer end of the socket. Removing the cold-chisel, I vinsert a mandrel in the eye, on the side opposite thatonivhich `the'punch entered, and give the exterior of' the socket the required form by means of swages, asseen'ini'g.2. v

The peculiarityciA my invention consists in the employment or use of the punch and die herein described, for forming the socket b ofthe stock, removed-in punching the eye e, and essentially accomplishing both at one and the'same operation. A I s A The advantagfes resulting are obvious. save from iive to seven heatings, and a large amount of valuable stock or material cnt awayand wasted by the old process informing the socket.` Y

The shoulders'm m of the punch A pass downto and rest on the shoulders u 11, ot' the die B, and when lso resting, the'lcwcr end,- o, of the punch A does not 'entirely reach to the bottom ofthe die B, but leaves suiiicient space to retain `the metal, as described in another part of this specification.

rformed, I wish tobe understnel that I ocket; nor do I intend to limi: al may be found to answer as Having thus (Iesoribed my invention, and how the same-is to be pe do not claim the providing of any particular tool or implement with an eye and s myself to steel as the substance of m'y punch land die, as some other mziteri weil; but Y What I do claim :xs-new, and forwhich I desire to secure Lefters Patent, is-

The combination of the punch A and die B, herein described, when constructed and operavti-ng substantially as and for the purpose set forth.
